One of the most complicated aspects of healthcare is the prior authorization process. Stricter rules imposed by payers for the year 2026, in addition to new types of authorization processes and the use of artificial intelligence to perform claim reviews, have compounded the potential for errors in obtaining prior authorization. Even small clerical mistakes made by a provider (or their staff) can lead to denials, treatment delays, or huge financial losses due to administrative error.
Healthcare providers need to be aware of the most common mistakes that occur in prior authorization and how to prevent those mistakes from happening in the future. To do this, the following lists highlight the most common errors a provider will face concerning prior authorization and possible methods to avoid them.
1. Submitting Requests Without Verifying Insurance Coverage
One of the most common prior authorization errors occurs when providers submit authorization requests without confirming patient eligibility or plan benefits. Insurance plans frequently change coverage terms, and some procedures require authorization only under certain plan types or policy conditions. When eligibility verification is skipped or incomplete, providers may submit requests for services that the patient’s plan does not cover. To prevent this issue:
- Verify patient eligibility before requesting authorization
- Confirm coverage details for the specific procedure
- Check referral requirements and network participation
- Document verification results within the patient record
Strong front-end verification significantly reduces avoidable authorization denials.
2. Lack of Documentation
Currently, in order for many procedures to be authorized by payers, they need to provide supporting evidence in the form of clinical documentation. The absence of supporting information or comments can lead to outright disqualification of a request. Some common areas where support documentation may be lacking include:
- Physician notes
- Diagnostic tests
- Reason for medical necessity
- Patient’s medical history or attempts at treatment
Oftentimes, providers end up resubmitting requests, resulting in unnecessary delays to patient care and in receiving payment.
3. Incorrect Procedure/Diagnosis Codes
An increasing number of errors happen at the time of prior authorization from coding, primarily as a result of payers continually updating their guidelines and coding rules. Examples of coding mistakes are:
- Utilizing previously used codes
- Using a procedure code that may not match the diagnosis code
- Unused modifier codes
- Incorrectly describing the service provided to the patient
If the provider’s code does not match the requested service in the authorization, the payer will typically deny the authorization.
4. Not Paying Attention to Each Payer’s Authorization Guidelines
Each insurance carrier has different requirements when it comes to prior authorizations for procedures. Some require extra information while others require formats for submitting or specific procedures to perform the review. Not adhering to payer-specific rules will result in many denials to the billing teams when submitting requests for authorization.
To avoid this problem, have updated payer policy guides available to all staff and ensure they are viewed frequently by your staff. Additionally, many practices keep an internal database to track changing authorization processes so they will have accurate information about what each payer requires at all times.
5. Poor Communication with Patients Regarding Prior Authorization Requirements
Many patients are not aware that prior authorizations are required for services. If authorization is delayed, the patient may get frustrated and may even cancel their appointment. Also, if you do not get prior authorization, the patient may receive an unexpected bill after the service. When communicating with patients, it is imperative that you use clear communication, explaining:
- The need for prior authorization
- The estimated time for receiving the prior authorization
- Letting the patient know that there is a delay in providing the prior authorization and/or the need for documentation.
- Information regarding possible limitations of coverage for that service.
By providing clear communication, you can help improve patient satisfaction and reduce the number of billing issues.
6. No Authorization Specialists
In many practices, the responsibility of obtaining authorization is given to staff members who have no or very little knowledge of the various payer rules. Without the proper knowledge, it is very easy for staff to forget or not get the appropriate paperwork necessary to obtain authorizations.
All practices should have the appropriate staff members who are dedicated to authorization management. These staff members can keep track of changes in payer rules as well as monitor and document all efforts to obtain authorization. Having an expert dedicated to the proper management of authorizations will greatly improve the accuracy of the approvals that are obtained.
7. Work Overload on Administrative Teams
Administrative teams have trouble processing a growing number of authorization requests in high-volume practices. As the number of patients rises, manual processing becomes harder to maintain. When administrative professionals are working overtime, they make errors and run late. Providers are now using prior authorization services to assist in managing these cumbersome workflows. These services will perform the following tasks as it relates to authorizations:
- Submit authorizations
- Verify documents
- Track statuses
- Appeal denied authorizations
By utilizing the assistance of a third-party, providers can alleviate administrative strain and increase the approval rates as it relates to their practices.
Role of Outsourcing in Reducing Errors in Prior Authorizations
As payers become more complicated in their adherence to policies and procedures, many healthcare organizations are attempting to outsource prior authorization functions. There are many benefits of outsourcing:
- Access to highly qualified authorization professionals
- Access to and trackability of dedicated systems
- Rapid response
- Reduced workload with in-house personnel
- Enhanced compliance monitoring
Outsourcing partners like RCM Workshop will focus on the authorization workflow, which gives in-house personnel the opportunity to improve quality patient care. Healthcare providers that invest in better tracking systems, staff training, and proactive authorization management will significantly reduce denials and improve operational efficiency.
For companies experiencing increased demand for authorization processes, using specialized prior authorization services or outsourcing their prior authorization processes to a partner can provide the level of expertise and scalability necessary to successfully comply with regulatory processes and continue to protect revenues.
